Early builds (08-09) on older software versions (060E, 080E, 100E) would likely be the ones that see measurable benefits rather than those M3s running later flashes. Still, it's a good idea to get updated to the latest version before applying aftermarket tunes.
But what about ESS tune? As Roman said its all up to date? Kill two birds with one stone or no?
